Few years ago my friend over-heated the engine in his '99 BMW 540i. Instead of attempting to repair any damage, he elected to just replace the engine. This left him with the old engine in his garage. I asked if I could have it, he obliged, and I got to work on it right away.
While my wife protested the idea of an engine block coffee table, she was okay with an engine block turned on its fly-wheel side, which resulted in a wine-bottle-holding end-table. And we all lived happily ever after.
